Summary

This document is the latest snapshot of the roadmap documents that has been presented to and adopted by WG 2 (ISO/IEC JTC1/SC2/WG 2). Four tables containing the roadmaps to

the Basic Multilingual Plane (BMP - Plane 0) (version bmp-4-6, 2003-10-22)
the Supplementary Multilingual Plane (SMP - Plane 1) (version smp-4-2, 2003-09-11)
the Supplementary Ideographic Plane (SIP - Plane 2) (version sip-4-1, 2003-05-16) , and
the Supplementary Special-purpose Plane (SSP - Plane 14) (version ssp-4-1, 2003-07-15)

are included in this document.

The Roadmap ad hoc group maintains and updates the roadmaps as a service to the UTC (Unicode Technical Committee) and to WG2. The latest working version of the roadmaps can be found at http://www.unicode.org/roadmaps. This document is informative. Please send corrigenda and other comments to the authors using the online contact form.

Presentation conventions

Conventions that are common to all the roadmap tables presented in this document are given below. Any additional conventions specific to a particular table are detailed after the heading for that table.

Published:
Bold text indicates an allocated (that is, published) character collection. There is a link to the corresponding chart on the Unicode web site. Note: For the CJK Unified ideographs in the BMP, the Unicode standards uses a single-column presentation. The multi-column presentation is available only in the published ISO/IEC 10646 standard and its amendments, available for purchase from ISO or various national standards organizations.
Accepted for inclusion:
(Bold text between parentheses) indicates scripts which have been formally accepted by UTC or WG 2 for processing toward inclusion in the standard. There is generally a link to a mature proposal for the script.
Under consideration:
(Text between parentheses) indicates scripts for which proposals have been formally submitted to the UTC or to WG 2. There is generally a link to the formal proposal.
Exploratory:
¿Text between question marks? indicates scripts for which detailed proposals have not yet been written. There may be a link to an exploratory code table.
Open:
??? in a block indicates that no suggestion has been made regarding the block allocation.

NOTE: When scripts are actually proposed to UTC or to WG 2, the practice is to "front" them in the zones to which they are tentatively allocated, and to adjust the block size with regard to the allocation proposed.

The size and location of the unallocated script blocks are merely proposals based on the current state of planning. The size and location of a script may change during final allocation of the script.

NOTE: As far as is possible, half-row (128) and surrogate block (4096) boundaries are observed in planning. This means that scripts do not cross these boundaries where possible.

Roadmap to the BMP

The following table comprises a proportional map of Plane 0, the BMP (Basic Multilingual Plane).

Areas containing RTL (right to left) scripts, as well as the Surrogates Zone (S-Zone of 10646) and the Private Use Area are shaded grey here informatively.

Roadmap to the SMP

The following table comprises a proportional map of Plane 1, the SMP (Supplementary Multilingual Plane).

The SMP is tentatively mapped out to the following zones (some of these zones are shown shaded in the table):

00010000-000100FF Linear B
00010100-000101FF Ancient numeric systems
00010200-000102FF unassigned
00010300-000107FF Alphabetic and syllabic LTR scripts
00010800-00010FFF Alphabetic and syllabic RTL scripts (shaded)
00011000-000117FF Brahmic scripts
00011800-00011FFF African and other syllabic scripts (shaded)
00012000-00012FFF Cuneiform and other ancient scripts
00013000-00013FFF Scripts for invented languages (shaded)
00014000-00016BFF Egyptian and Mayan hieroglyphs
00016C00 00016FFF Aztec pictograms (shaded)
00017000-0001B5FF Large Asian scripts
0001B600-0001CFFF unassigned (shaded)

Roadmap to the SIP

The following table comprises a proportional map of Plane 2, the SIP (Supplementary Ideographic Plane).

Plane 2 is tentatively mapped out to the following zones:

Changes in this document from document N2559 of 2002-12-06

Updated the status of all scripts that have been published in Unicode V4.0, and in ISO/IEC 10646 or its final amendments (two of which were under FDAM ballot as of WG2 meeting M44 that ended on 2003-10-23). Links have been updated to point to the relevant charts at the Unicode web site for all the published scripts.
Updated the status and document links for Buginese (row 1A), Glagolitc (row 2C), Coptic (row 2C), Georgian Supplement (row 2D), Supplemental Punctuation (row 2E), Siloti Nagri (row A8), and Phags-Pa (moved to row A8 from row AA), which have reached 'Accepted Status' at meeting M44.
Updated links to latest proposal documents for several scripts.
Several minor editorial changes to the text have been made.
The online contact form is pointed to as the feedback mechanism for comments on this document.
BMP - Added C0 and C1 entries in Row 0 (* these are not in the roadmaps on Unicode web site).
BMP - added Arabic Extension in Row 07.
BMP - moved Phoenecian from BMP Row 08 to SMP Row 09.
BMP - adjusted space for Buginese (was Lontara) and adjusted the rest of the row 1A.
BMP - provided four more columns for Phonetic Extensions, added Combining Diacritics Supplement (displacing Alphabetic Extensions) in row 1B.
BMP - moved Pollard to BMP Row A7 from SMP Row 04
BMP - moved around rows A8, AA and AB row contents.
SMP - several non-standardized scripts have been moved around.
SMP - Added Archaic Greek Musical Notation to Row D2.
SMP - Added Anicent Greek Numbers to Row 01.
SIP - Added NOTE about possible use of Plane 03 for allocating additional Han Ideographs should the need arise.
SIP - Adjusted the end of range for CJK Extension B to reflect standardized columns in Row A6.
SSP - Row 01 - "Variation Selectors"renamed "Variation Selectors Supplement" and Range adjusted to show standardized columns.

Changes in this document from document N2461 of 2002-05-14

Rows 07 and 08 in BMP: Shuffled around Madaic, N'Ko and merged Avestan and Pahlavi.
Rows 19 and 1A in BMP: Shuffled Tai Lue and Viet Thai; added more Khmer in empty columns in 1A.
Row 1D in BMP: Renamed UPA Extensions to Phonetic Extensions and extended into empty columns in left half; Used up empty columns in right half for Alphabetic Extensions.
Row 03 in SMP: Updated doclink and renamed Old Persian.
Row 04 in SMP: Updated doclink for Osmanya.
Row 06 in SMP: Added doclink for Bassa.
Row 0B in SMP: Added Manichaean to left half moving Orkhon and Yezidi to right half.
Row 12 in SMP: Added doclink for Rejang.
Row 2F in SMP: Added missing doclink for Indus; Row 2E had the link.
Row D3 in SMP: Updated doclink and status for renamed Tai Xuan Jing Symbols.
